A practical guide

A blockchain is a record shared across a network of computers. Transactions are grouped into blocks; each block refers to earlier data, making later changes detectable. Participants follow a consensus process to decide which valid block comes next. The exact rules depend on the network.For a related explanation, read {how cryptocurrency uses ledgers|crypto} and {what network nodes do|nodes}.how cryptocurrency uses ledgerswhat network nodes do

What to know

A blockchain can make records independently verifiable, but it does not make every application decentralized, private, or error-proof. A project may use a public chain, a permissioned network, or no blockchain for a particular feature. Those details should be checked for the specific product rather than assumed from its marketing.UIGame’s public information describes {UIGT as a game token|uigt}; it does not require readers to treat gameplay as investing.UIGT as a game token

Using this information

For gaming, the practical questions are simple: what does a token do, which rules govern a game, what costs apply, and how can a player protect an account? A blockchain concept can help explain digital records, but it cannot predict a game outcome.
